Referring to the drawing, the reference char V .acter )3 indicates the razor guard element, ll

Ifthecap is made of plastic material, it'is to be inibedded inthe body ofsaidcap element when-the latter is molded. The 'cap ement l2 7 V is. further providedwith "guidapins il5' spaced outwardly of the coup1in gstud,'a nd also disposed ;t0 project1from the inner or under face of said cap element for extension through correspond; ing' openings in the guard felement' 0 provided thereforp i The razor blade ll is centrally'perforatedin any wcll'knownmanner, wherebyto permit pr0- jection [of the cap' guide pins l I 5 and coupling stud i 3 therethrough; s'o that "the blade may i be here involved. 1

The collapsible handle elehfient of therazor, in an illustrative iormthereof as shownmomprises f a an inner niemb'er'lfiand a tubular outer member l1. Said 'outerinernber isprovided'with an in-, ternalbore"lflinwardly''tapering'irorn itsfouter toward its inner end. The inner 'member l6 is I .provided with a correspondingly; tapered exter nalsurface='l-9;likewisetapering from" its "outer toward its-innere'nd, jbut said'in'ner memberlfi' is' somewhat smaller i minorand majordiam eters' than] the corresponding-minor and major i 1" diameters of theouterrheniber'bore l8, so that V said inner-rnernber is'telescopically projectable frjorn the-inner or smallyend of the outer member here, until stopped by the meeting ofgits tapered surfac'efiyvith that ofsaidfborel member n45 a longitudinally disposed'key way channel 20. Formedto projectfrom the tapered surface 1190f the inner member 16 is a longitudinally extending key formation, the same being meqm the'wallhoi." the bore l ll or theouter pl'edto the gua preferably molded w th the inner member 15 as an integral part thereof.

The inner handlememberii'i is assembled with the outer handle member il'by passing the former, small end first, through the outer open end of the latter and'into the bore 18 thereof,

and so that the key formation 2| oi." said inner a member slidably engages in the' keywaychannel l as of said outer member.

After the inner member i6 is inserted into the outer member H, the outer open end of the latter.

is closed by a closure plug '22 which is inserted and cemented'thereto, and, consequentlm akq:

though said members I6 and ilmay be relatively moved longitudinally to permitsuitably limited projection of one relative to the other, bodily separa ion or displacement of the one fromfthe" other is prevented.

- Molded into theinner or small end of said inner member i5 is a metallic coupling bushing 23' having an internally screw-threaded bore 24 adapted; at. proper times; to receiveand screw onto the coupling-stud it of guard,,blade and cap assembly; Inpractice"the outenmember H of the han- .dle elementjis niacie I of -;a liength'approximating V ladeand cap assembly, I
